IMPROVEMENT IN SEWING-MACHINES.

Specification forming part of Letters Patent No. 130,775, dated August20, 1872.

To all whom it may concern:

Be it known that I, AUSBERT H. WAGNER, of Chicago, in the county of Cookand in the State of Illinois, have invented certain new and usefulImprovements in Sewin g-Machines; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing making part of this specification,in

' which the employment of a detachable shoulder or lip upon the verticalside of the shuttle-race, and immediately in front of the needle-way,substantially as and for the purpose hereinafter specified.

In the annexed drawing, A represents the horizontal and B the verticalportions of the shuttle-race frame,between or within which is formed therace C, of usual form. From the upper edge of the part B a plate, b,extends horizontally outward over a portion of the race C, and acts as aguard or stop to prevent the shuttle from vertical displacement. Theneedle-way D passes downward through the plate b, the inner faceof thepart B, and through the lower part or base A, and has the usual form,except that within the part B. Said opening is extended forward, so asto receive a smallplate, E, which has the general form shown in Figs. 1and 3, its edge adjacent to said needle-way being extended downward andrearward in a curve, while the loweredge of said part inclines slightlyupward and rearward. The curved edge of the plate E is beveled outward,while its point 0 extends partially over the needle-way, and is recessedout upon or within its rear side, so as to form of or from said point alip or shoulder, which re ceives and contains the thread, andeffectually prevents the same from being moved forward by the shuttle asit passes through the loop. By means of this device, a failure to make astitch by reason of the displacement of the loop by the shuttle isavoided, and one of the most serious objections to the employment of ashuttle removed.

Having thus fully set forth the nature and merits of my invention, whatI claim as new,

In a shuttle-race, a detachable lip or shoulder, extending over andpartially inclosing the needle-way, substantially as and for the purposespecified.

In testimony that I claim the foregoing I have hereunto set my hand thisliith day ot June, 1872.
